Overview of the scenarios for the ABC analyses. The scenarios depict one or two colonization events of red deer to Norway and estimated population sizes shown in different colours. t0 – t3 indicate DNA sampling points in time and are marked by circles. Note that we allow the sampling at t2 in scenario II to occur either before or after the admixture event. tD denotes the divergence time of the Norwegian population, while tBS and tBE marks the start and end of the estimated population bottleneck respectively.
